To all 'whom t may concern:

Be it known that I, OrroMARS'rANGE, a

citizen of the United States, residing at D Aspinwall, in the county of AAllegheny and State of Pennsylvania, have invented cer.

tain new and useful Improvements in Concrete Piling, of which the following is a specification.

This invention 'relatesto a splice for sec:

tional piling made .of concrete, or othercementitious material, a4 d it has for its object to provide a rigid a d suiliciently strong connection, lor cou ling for the sections where existin con' itions prevent placing pilingv of the ll length required, and driv- 1ng,jetting and jacln'ng down the same to their ultimate position.

In the accompanying drawing forming a part of this specification-Figure 1 is an elevation of a spliced pile :driven to its required depth. Fig. 2\ is asvertical section of va ile being driven showing two sections driven and the third section ready to be placedin position for driving. Fig. 3 is a perspective view of the splice.

Referring specifically to the drawing, 1 designates a coupling band or ring of suitable metal which, as sholwn', is round, but which may be of any other suitable shape" to-fit the design of the pile for whichit is intended. This coupling band is placed on the lower end of each section 8 of piling except the first section, andis secured to the section at the time .of casting with its outer surface flush with thelouter-surface of the section. The end of the section lis reduced in diameter to form ashoulder `2' against which the upper end of the band' abuts. The other end of the band extends. 40 from the section so that it mayv be slipped over the upper end of the next section below,

- the latter also having a shoulder 2f formed by reducing its diameter at this, end, against which shoulder the lower end ofthe band abuts. A suitable reinforcement 3- is .em-

bedded in the sections and may be of various designs and sizes to meet existingconditions. Onthe lower end of the bottom section is a shoefi which is also designed to meet existing conditions. A cushion 5 of cement, mortar or mixture of other cementitous material is placed on the top of the section already driven and remainsin place after the 'act of splicing, the same forming 55 a vfiller for the joint and preventingvoids between the sections. The measurements of the batters 6 and 7 on the bottom Section', from the point to the rst splice, depend on the requirements in each case. It isv desirable to have the splices conform to a r` quiredbatter.

The splice connecting the 'various sections allows driving andplacing the piling under trestles, buildings and other structures, where there is a lack o f suicient head room to use 'avpile of the exact length required. By using the 4splicefthe various sections can readily lbe placed and driven', jetted `or jacked downto the lrequired de th. Another advantage ofthe splice is t at it en- 7 ables sections of standard size' and lengths to be cast and kept in stock for future use,

thus insuring at any time vanA opportunity for prom t assembling lof piling thoroughly seasoned v vnd adaptable to any requirement. 4

Thea vantage of having a stock of-piling which is thoroughly seasoned and ready to use is evident, and it is an .important -fac tor-in all cases in which concreteor other l piling of .cementitious material is used. .30

Should a certain .length or lengths of piling be specified,` and subsequently be cast and seasoned for a proper length of time, and upon driving it is desired for any reaev son to place4 them to a' greater -depth than originally specified, it is possible with the splice to add such length or lengths as will be necessary to meet the requirements. The splice binds the sections firmly together, making a practically solid piece* of ,the joined parts, andjcausing them toact as a unit. 4

The material 5 is placed on top of the section driven, before the section on which the splice is fastenedis placed `upon it,'and 95 said material takes up all unevennessof -surface, and acts as a cushion to the-pressure or force applied in driving the sectin, and

-prevents a crushing of the material where the edges meet, -All measurements and sizes are to be governedkby the conditions of work, nature of ground, and. loads to be superimposed.

-A pile ,comprising solid sections of cementitious material, said sections being longitudinally alined, a cushioning body and filler located between the ends of .adjacent sections, and a splicing band carried by. yone section and projecting from the end thereof, `the. other Vsection having` r a circumferentally' reduced portion andashoulder at the inner end-thereof, said band project-V ing beyond the end of that section on 'which it is mounted for a distancegreater than the distance between the end of the other section and its shoulder, whereby ythe re' duced end portion is received Within the band and the end thereof engages the shoul-l der, and space is left between the two secl tions' in which the aforesaid cushioning body andller is confined b the-band.

In testimony whereof Il ax my signature in presence of two witnesses.
